TCAAP Energy Integration Resiliency Framework Energy Source Implementation 50 Total System Capital Cost Comparison District Energy Capital Costs Traditional System Capital Costs Pump Station $375,950 Xcel Energy Infrastructure $0 Distribution Pipe $2,527,500 Service Laterals $533,200 Domestic Water Heaters $493,000 Domestic Water Heaters $591,600 Heat Pumps $2,563,000 High Efficiency Furnaces $1,005,720 AC Units $1,135,872 Total $6,493,250 Total $2,733,192 Table 17: Total system capital cost comparison For the economic analysis, the Project Team assumed that the district energy facilities at the energy transfer station and the distribution piping would not be paid for by the TCAAP developer. Typically, the district energy entity pays for the production and distribution facilities. The Project Team did assume that the developer would pay for the procurement and installation of the heat pumps, and hot water heaters in the homes. The Project Team also assumed that the developer would pass the minimal additional cost of the heat pump installation on to the homeowner through an increased mortgage amount, and would be able to use the eco-friendly aspects of the system as a selling point. The analysis was completed for straight costs, and did not include any rebates or tax credits that may be applicable for these energy efficient homes. A summary of the initial costs to be paid by the developer is shown in Table 18.
